Astronomers have discovered that the Small Magellanic Cloud, a nearby dwarf galaxy, is being torn apart by the gravitational pull of its larger neighbor, the Large Magellanic Cloud.

By tracking thousands of massive stars, researchers found that the galaxy lacks rotational motion and shows signs of disruption, which could dramatically shift our understanding of how galaxies interact and evolve. This discovery offers a rare real-time look into the cosmic tug-of-war that may have shaped galaxies in the early universe.

Gravitational Tug-of-War Between Galaxies.

K2-360 is a newly found planetary system with a super-dense planet, likely the core of a former larger world, shaped by dynamic interactions with its companion. An international team of researchers from Japan and Europe has discovered a new multi-planet system orbiting a Sun-like star. Among the

Researchers mapped a far-infrared landscape brimming with nearly 2,000 galaxies. There may be “hidden galaxies” lurking just out of sight.

For generations, sailors around the globe have reported a mysterious phenomenon: Vast areas of the ocean glow steadily at night, sometimes for months on end. The light is bright enough to read by and is oddly similar to the green and white aura cast by glow-in-the-dark stars that have decorated children’s rooms. Stretching over ocean space as broad as 100,000 square kilometers, the light can, at times, even be seen from space.

This rare bioluminescent display was coined by sailors as “milky seas.” Despite being encountered for centuries, scientists still know very little about what causes this glowing effect because they are quite rare—they usually occur in the remote regions of the Indian Ocean, far from human eyes. A likely theory is that the glow comes from activity by a luminous microscopic bacteria called Vibrio harveyi.

To better predict when milky seas will occur, researchers at Colorado State University have compiled a database of sightings over the last 400 years.
